This study was conducted to investigate the effects of diet and exogenous enzymes on growth responses and micronutrient digestibility of broilers. Day-old broilers (n = 256) were distributed into a 2 x 2 factorial design and were fed on two basal diets: soybean (T1) or canola (T2) meals as such, or supplemented with enzymes up to 21 days. Feed intake (FI) and live weight (LW) to 21 days on the T2 diet was higher (P < 0.001) than that on T1. Feed conversion ratio (FCR) was better (P < 0.01) on T1 than on T2 at 21 days. Enzymes generally improved (P < 0.001) FI, FCR, and LW. The digestibility of histidine was higher (P < 0.05) on T2, but lysine digestibility was higher (P < 0.01) on T1 at 21 days. Histidine, threonine, lysine, valine, isoleucine, and phenylalanine digestibility was improved (P < 0.05) in the supplemented diets. Mineral digestibility was unaffected (P > 0.05) by diet, but enzymes increased (P < 0.05) digestibility of P, K, Mn, and Cu at 21 days. The digestibility of Cu, Zn, and Mg was higher (P < 0.05) on T2, whereas Ca digestibility was greater (P < 0.05) on the T1 diet. Broilers' growth responded positively to enzyme diets, probably due to improvement in nutrient digestibility.

Growth and carcass characteristics of Honamlı, Hair, and Honamlı x Hair crossbred goat kids were investigated in this study. Seven kids, having live weights between 25 and 30 kg, were slaughtered. It was found that the live weights of Honamlı, Hair, and Honamlı x Hair kids were 3.90 kg and 27.50 kg, 3.04 kg and 16.91 kg, and 3.58 kg and 22.07 kg at birth and on the 120th day, respectively. Honamlı kids had higher body measurements, as well as birth and live weights, when compared to the other genotypes. While flocks had an important effect (P < 0.001) on all growth periods, the effect of dam age on body measurements was also significant (P > 0.05), except on …
